QUESTION 13 Given the volume of the standard hydrochloric acid used in titrating the analyte to reach the endpoints of phenolphthalein and methyl orange. Determine the composition of the base/s in the unknown sample. - v 12.50 ml HCI to reach A. sodium carbonate phenolphthalein endpoint, and 0.05 mL to sodium bicarbonate reach methyl orange endpoint B. sodium hydroxide and C. sodium bicarbonate Indicators were added D. sodium bicarbonate and one after the other and it sodium carbonate was observed that 8.50 E. sodium hydroxide and ml HCI to change the unknown solution from F. sodium hydroxide pink to colorless, and 15.05 mL to reach turn the solution into salmon sodium carbonate pink solution. The first indicator became colorless outright. The next indicator required 14.00 mL to reach turn the colorless solution into salmon pink solution. In both segments in titrating the unknown base sample, the standard solution gave almost the same amount of titrant consumed after each addition of the indicator
